the interaction of anticancer drug sn (ch3)2(n-acetyl-l-cysteinate) with carbon nanotube (cnt)is investigated by quantum chemical ab initio calculations at fif/ (lanl2dz+sto-3g) and hf/(lanl2dz+6-31g) levels in gas phase and solution. the solvent effect is taken into account viathe self-consistent reaction field (scrf) method. carbon nanotubes can act as a suitable drugdelivery vehicle for inte...

normal 0 false false false en-us x-none ar-sa background: t he study on transcranial sonocraphy (tcs) as a diagnostic test for parkinson’s disease (pd) has been neglected in some hospitals. the current study was conducted as the first study to investigate the utility of tcs for diagnosis of pd and its ability to distinguish pd from essential tremor (et) in an iranian population. materials and m...

The changes in microstructure and microhardness of Sn-0.5%Ag, Sn-1.0%Ag, and Sn-0.7%Cu Pb-free solders were investigated during high temperature aging at 200°C for 2 h. As-solidified microstructures, revealed by cross-polarized light microscopy, consist of relatively large grains of β-Sn phase with twinned microstructure in both Sn-Ag and Sn-Cu solders. The bright-field light microscopy display...

The structures of medium sized tin cluster anions Sn(n)(-) (n = 16-29) were determined by a combination of density functional theory, trapped ion electron diffraction and collision induced dissociation (CID). Mostly prolate structures were found with a structural motif based on only three repeatedly appearing subunit clusters, the Sn(7) pentagonal bipyramid, the Sn(9) tricapped trigonal prism a...

  Data envelopment analysis (DEA) is a nonparametric approach to evaluate theefficiency of decision making units (DMU) using mathematical programmingtechniques. Almost, all of the previous researches in stochastic DEA have been usedthe stochastic data when the inputs and outputs are normally distributed. But, thisassumption may not be true in practice. Therefore, using a normal distribution wi...

As only about 20% of sentinel node (SN) positive melanoma patients have additional non-SN lymph node involvement in the Completion Lymph Node Dissection (CLND) specimen, we tried to identify a SN positive patient group, which can be spared CLND. Micro anatomic analyses of metastatic SNs were performed to identify patient/tumor and/or SN factors predicting additional non-SN positivity as well as...
